In the aftermath of a global pandemic, a beautiful and charismatic human rights activist is murdered live on the internet at the British Embassy in Paris. It is a mystery that no one wants solved.

When governments refuse to investigate, Ambassador Ed Barnes is determined to find out the truth himself. The quest for answers plunges Barnes deep into a world of cyber terrorists and warlords, taking him to Oxford, Copenhagen, the mountains of Snowdonia and Lebanon, where he picks up the trail of a shocking conspiracy.

This is an international crisis - but also a personal one. Only Barnes can save his family, his diplomatic service and even his country. But can he save himself?
